You have an RC circuit and you measure the "zero" voltage to actually be 2.385 [Volts]. The peak voltage is measured to be 8.262 [Volts]. At what voltage value will you look for t4 = time stamp for 15/16 total charge?

## physics

The electric field in an xy plane produced by a positively charged particle is 14.2(4.4 + 3.3) N/C at the point (3.1, 3.7) cm and 117 N/C at the point (3.2, 0) cm. What are (in cm) the (a)x and (b)y coordinates of the particle? (c) What is the charge (in
